Sorry I haven't been here much, but between a really funky job market, and now having a Royal Majesty Prince V, time's been a bit lacking!
Well, onto the questions:
I've got two SDRAM chips I can't quite identify. They're definitely older units.
I've been using Everest Home Edition v2.20, and if you go to Motherboard -> SPD, it'll list the RAM modules installed, and give you quite a bit of information, most importantly to my question Memory Timings.
I'm using a P2-266 as my test-mule, and have thus gleaned quite a bit of info about some old DIMMs that I have (including a 4-chip, single-sided 32MB piece that's brutally fast at 100MHz . . runs 2-2-2-5, which I didn't think such small modules were available at).
Anyway, there are two DIMMS I have that Everest can't identify. One of them is lacking that little SPD chip, though strangely, the other one has one, but Everest still simply won't list it at all.
So, what I'm wondering is, does anyone know, or is there any free software out there, that will tell me what memory timings these two DIMMs will run trouble-free at a given FSB?
The one without the SPD chip has NEC chips, 32MB total, 16 chips (8 on each side), with the following markings:
Code: Select all
NEC JAPAN D4516821AG5 -A10-7JF 9805AY007
There are also 2 stickers on it, each of which fits onto a single one of the chips, one of which reads:
and the other:
The second DIMM I think is a PC66 unit, though I've come across references stating that some PC66 modules will perform better than some PC100's. This is the one that has an SPD chip on it, but Everest acts as if it doesn't. It's also a 16-chip unit (8 chips on each side), and 32MB. Anyway, the chips on this one read:
Code: Select all
KOREA C206 9819 FFF0 HM5216805TT10H
Void if Removed
and the second of which spans 4 of the chips and reads:
(a UPC bar code, with the following numbers under it: 0 75028 00000 4)
Also printed on the corner directly on the module is:
ASSY IN USA
I've done quite a bit of searching on Google, but it's been mostly fruitless, other than that the former has NEC chips (duh) and is PC100, the latter has Hitachi chips (most likely), and is probably PC66.
Anyone have access to datasheets, or know where I can get software that will definitely identify the SPD-equipped one? I tried searching Hitachi's and NEC's websites to no avail. My goal is really to find out what the ideal timings are at a given FSB.
